Description

a dishwasher

technical field

The invention relates to a dishwasher, which belongs to the field of household washing.

Background technique

Compared with household appliances such as color TVs, refrigerators, and washing machines, household appliances such as dishwashers are still under development. Modern family life requires a dishwasher that meets family needs in terms of the number and types of bowls stored, meets domestic family dining requirements in terms of the cleanliness of bowls and chopsticks, and is digital and intelligent in terms of use.

At present, dishwashers are still in the stage of commercialization. The washing method is mainly water pressure washing, which occupies a relatively large area, and the investment and use costs are high. They are often used in public restaurants and hotels. Because Chinese families are accustomed to using porcelain bowls, the shapes and sizes of the bowls vary greatly, and there are various types of food and cooking methods. The food is greasy and sticky, and it is particularly difficult to clean, which makes it necessary to wash the bowls and chopsticks. The method, time, water consumption, and the impact force that the bowls and chopsticks can withstand are very different. In addition, Chinese families like to eat multiple dishes at one meal, and the living habit of one dish is one bowl, and the amount of rice bowls used for one meal is relatively large. There is no better solution for household dishwashers. In addition, the price of existing household dishwashers is relatively high, and special detergent must be used. The price of single use is high, and it is easy to pollute the environment. The promotion of domestic dishwashers has been Great resistance.

With the advent of a well-off society, housework will inevitably tend to be automated. Washing dishes is an indispensable labor task in housework and an indispensable link in family life. But washing dishes is often one of the most annoying things in housework. Automatic dishwashing should be an urgent need for every family. Household automatic dishwashers will definitely become an indispensable household appliance in Chinese family life.

A dishwasher includes a box body, a power device, a rotary transmission drive device, a swing transmission drive device, a cleaning device, a bowl, a bowl basket, a rotary transmission drive device, a swing transmission drive device, and a control device connected to the power device. The cleaning device and the bowl basket are located in the casing, and the bowl is placed in the bowl basket. The cleaning device comprises a rotating brush and a swinging brush, the bowl basket is located between the rotating brush and the swinging brush, and the bowl is located in the bowl basket. The rotating brush includes bristles and a rotating brush body, and the bristles are installed on the rotating brush body. In further improvement, the bristles are evenly distributed on the rotating brush body. The oscillating hairbrush includes bristles and a oscillating hairbrush body, and the bristles are installed on the oscillating hairbrush body. Further improvement, multiple rows of bristles are installed on the oscillating hairbrush body. The bristles on the rotating and oscillating brushes are in contact with the bowl. The rotary transmission driving device is connected with the rotary brush, and drives the rotary brush to rotate eccentrically. The oscillating transmission driving device is connected with the oscillating brush, and drives the oscillating brush to perform reciprocating linear motion. Because the rotating brush rotates eccentrically, the rotating brush not only rotates but also moves up and down, left and right, and the bristles on the rotating brush scrub the inside of the bowl with the movement of the rotating brush, forming an action of imitating human hand scrubbing the bowl, which can effectively Brush off hardened leftovers that have stuck to the bowl. Due to the reciprocating linear motion of the oscillating hairbrush, the bristles installed on the oscillating hairbrush scrub the outside of the bowl by reciprocating swinging. The surface of the side on which the bristles are installed on the rotating brush body is uneven in thickness and is in a large wave shape. When the rotating brush is turned, the water is stirred in a spiral manner, which can not only stir the water in the water tank to form waves to move toward the inside of the bowl, wash away the bowl and the tank, and make the stains under the brush float. Moreover, all the bristles can be moved to form an action of rubbing and scrubbing bowls imitating human hands. The surface of the side on which the bristles are installed on the oscillating brush body is in a small wave shape. The oscillating brush has the effect of blocking the waves, generating turbulence, causing the waves to form a rotation and impact the bowl surface, which can wash away the stains on the bowl. Rotating brushes and oscillating brushes, one rotates and the other moves, agitates the water in the case, and continuously washes the surface of the bowl, so as to realize the cleaning of dirty bowls in various cooking methods. Only half a tank of water is needed in the box. The two brushes rotate while sweeping, agitating half a tank of water in the dish basin, and continuously flushing the bowl surface. Since the rotating brush is half immersed in the water, the bristles will throw water droplets and hit the bowl surface when rotating, so as to clean the bowl. surface function.

As a further improvement of the present invention: the end surface of the side on which the bristles are installed on the rotating brush body has an angle of inclination of 5-10 degrees with the horizontal plane. This design can better stir the water in the water tank to form waves moving in the direction of the bowl.

As a further improvement of the present invention: the bowl basket bracket of the bowl basket is a hollow tube, and a water outlet hole is opened on the hollow tube, and the hollow tube is connected with a water inlet pipe. A water outlet hole is provided on the hollow tube to allow water to clean the inside of the bowl and the sides of the bowl, ensuring that there is no dead angle in the bowl that cannot be washed.

As a further improvement of the present invention: the rotational speed of the rotating brush is 53.3r/min, and the speed of the oscillating brush is 72.6 times/min. After testing, the mutual cooperation of the two speeds can make the cleaning effect reach the best.

As a further improvement of the present invention: the control device is a PLC controller.

As a further improvement of the present invention: the PLC controller has two gears, manual and automatic.
